## Inline popups

An inline popup places the popup content inside the current page, hidden from the view. For example, this container will not be visible on the page.

```html
<div class="control-popup modal fade" id="contentBasic">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-body">
                <button type="button" class="close" data-dismiss="modal">&times;</button>
                <p>This is a very basic example of a popup...</p>
            </div>
        </div>
    </div>
</div>
```

Use the `data-toggle="modal"` HTML attribute to launch this container as a popup.

```html
<a data-toggle="modal" href="#contentBasic" class="btn btn-primary btn-lg">
    Launch basic content
</a>
```

<a name="remote-popups"></a>
## Remote popups

Content for the popup can be loaded remotely using an AJAX request. Use the `data-handler` attribute to populate a popup with the contents of an AJAX handler.

```html
<a
    data-control="popup"
    data-handler="onLoadContent"
    href="javascript:;"
    class="btn btn-primary btn-lg">
    Launch Ajax Form
</a>
```

Using the `data-ajax` attribute you can refer to an external file or URL directly.

```html
<a
    data-control="popup"
    data-ajax="popup-content.htm"
    href="javascript:;"
    class="btn btn-primary btn-lg">
    Launch Ajax Form
</a>
```

The partial for your rendered popup should follow this structure:

```html
<div class="modal-header">
    <button type="button" class="close" data-dismiss="popup">&times;</button>
    <h4 class="modal-title">
        <!-- Modal header title goes here -->
        Send email
    </h4>
</div>
<div class="modal-body">
    <!-- Any popup content goes here -->
    <?= $this->customFormWidget->render() ?>
</div>
<div class="modal-footer">
    <!-- Popup action buttons go here -->
    <button
        type="submit"
        class="btn btn-primary oc-icon-send"
        data-load-indicator="Sending">
        Send
    </button>
    <button
        type="button"
        class="btn btn-default"
        data-dismiss="popup">
        <?= e(trans('backend::lang.relation.close')) ?>
    </button>
</div>
```
